Abstract

A timepiece including hour and minute hands of different configurations which are operated in a time-maintaining mode through the intermediary of a clockwork.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. Timepiece including hour and minute hands possessing differing configurations; a dial face place structure; a clockwork operating said hands in a time-maintaining manner, said clockwork being supported on the rear of said dial face place structure, said hands displaying equal lengths in the direction of viewing towards said timepiece; a circular minute-scale arrangement, on said face place structure, said hands extending close to an inner circular edge of said minute-scale arrangement and at least one of said hands extending into proximity with said minute-scale arrangement in the plane of the latter, said dial face plate structure having a cylindrical wall structure forming a hollow cylindrical depression, said hands rotating within a narrow cylindrical space formed by said depression, and extending into close proximity with the hollow cylindrical wall structure of said depression. 
     
     
       2. A timepiece as claimed in claim 1, wherein the depression is surrounded by said minute-scale arrangement. 
     
     
       3. A timepiece as claimed in claim 1, comprising a clock glass covering said hands and having an opaque cover in the center thereof. 
     
     
       4. A timepiece as claimed in claim 2, wherein said depression annularly surrounds said minute-scale arrangement in a viewing direction facing the timepiece. 
     
     
       5. A timepiece as claimed in claim 1, comprising an opaque disc in the central region of the timepiece in a in front of said hands. 
     
     
       6. A timepiece as claimed in claim 5, wherein said minute-scale arrangement is provided along the edge region of said disc. 
     
     
       7. A timepiece as claimed in claim 1, wherein resilient latching arms retain said clockwork in a hollow space behind said dial face plate support, and a bottom closure for closing said hollow space in the region of the rear plane of the clockwork. 
     
     
       8. A timepiece as claimed in claim 3, wherein the support for the dial face plate comprise a base member with a laterial plate-like surrounding socket portion and an axially-parrallel protruding rim, and a disc-shaped dial face plate having an inner circular rim determining the diameter of the depression visible through said clock glass, and said hands rotating within the depression. 
     
     
       9. A timepiece as claimed in claim 8, wherein a shutter engages the support for the dial face plate within the inner cicular rim of the dial face plate at the bottom of the depression. 
     
     
       10. A timeplate as claimed in claim 9, wherein the dial face plate and the clock glass possess substantially equal diameters and are arranged above each other within the depression. 
     
     
       11. A timepiece as claimed in claim 9, wherein said clock glass is arranged generally in the plane of the dial face plate and is retained along the inner circular rim thereof. 
     
     
       12. A timepiece as claimed in claim 8, wherein a hollow cylindrical offset engages the inner circular rim of the dial face plate. 
     
     
       13. A timepiece as claimed in claim 12, wherein the cylindrical offset contacts the bottom of the depression, and a plate-like shutter being clamped by said offset. 
     
     
       14. A timepiece as claimed in claim 1, wherein said dial face plate support includes a base member with a rearward cylindrically projecting region, and gripping depressions formed in an outer casing surface of said base member to facilitate handling of said timepiece.
